introduction:QD802 series crane dedicated inverter is a high performance vector frequency converter, Ao Zhuo technology company for hoisting industry professional design, used for all types of crane hoisting, pitch, amplitude, cart, trolley, rotation, grab institutions such as communication, stepless speed regulation.

Features:Complete logic brake function, effectively avoid the slip phenomenon of hookThe second motor parameter function, time-sharing one driving two functionswith a wide range of ways Low torque compensation under the VVVF control collision stop function and realize the safety limit instantaneous stop non-stop function, without tripping operationThe overload protection function, after the overload limit is runningAbnormal frequency function, when the feedback speed and set up automatic alarm when deviation beyond the limitLow parameter copy function, improve the efficiency of multiple set of system parameter Settings, avoid the artificial parameter errorsProtection timely, reliable and low control system stability is highmore productscan realize common dc busS curve deceleration function, make more smooth start and stopcompatible European level interface standards
